Autophagy as well as Mitophagy as Essential Aspects of Illness.
To investigate the efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of acute monocytic leukemia (AML-M5) and the related factors that affecting the prognosis of the patients.

The clinical data of 71 patients with AML-M5 treated with allo-HSCT in Zhujiang Hospital Affiliated to Southern Medical University from April 2009 to October 2019 were collected and retrospectively analyzed. The incidence of graft-versus-host disease (GVHD), cumulative overall survival (OS) rate, cumulative progression-free survival (PFS) rate, transplantation-related mortality (TRM), relapse rate and the risk factors affecting prognosis in the patients were analyzed.

66 patients obtained hematopoietic reconstruction after transplantation, the median time of granulocyte implantation was 12 (9-26) d, and the median time of megakaryocytic implantation was 13 (8-72) d. The incidence of acute GVHD and chronic GVHD was 33.8% (24/71) and 36.6% (26/71), respectively. The median follow-up time wasn relapse and invasive fungal disease after transplantation are the important factors affecting the efficacy of allo-HSCT in patients with AML-M5.
AML-M5 is the intermediate or high-risk leukemia, and allo-HSCT can improve the survival prognosis of the patients. Pre-transplantation relapse and invasive fungal disease after transplantation are the important factors affecting the efficacy of allo-HSCT in patients with AML-M5.
To investigate the effect of miR-29b-3p on apoptosis and proliferation of acute myeloid leukemia (AML) cells by targeting signal transducer and activator of transcription 3 (STAT3).

TargetScan and miRanda online databases were used to predict the binding sites of miR-29b-3p and STAT3 3'UTR. The targeting relationship between them was estimated by Dual-Luciferase reporter assay experiment. After miR-29b-3p over-expression, qPCR and Western blot were used to detect the expression of STAT3 mRNA and proteins, flow cytometry to determine the apoptosis of AML cells, and MTS to detect the changes of cell proliferation in each group.

Dual-Luciferase reporter assay confirmed that STAT3 was the target gene of miR-29b-3p. see more After miR-29b-3p overexpression, the expression of STAT3 mRNA and protein decreased. Compared with the control groups, the proliferation of AML cells in the overexpression group decreased and the apoptosis increased (P<0.05).

MiR-29b-3p can inhibit the proliferation and induce apoptosis of AML cells by down-regulating STAT3.

To analyze the characteristics of volatile organic compounds (VOCs) in expiratory air components of patients with acute promyelocytic leukemia (APL), and assess the feasibility of VOCs for the diagnosis and prognostic evaluation of APL.

The VOCs exhaled from the patients with APL and healthy volunteers should be analyzed with SPME-GC/MS, and compared between newly-diagnosed group, relapse group, remission group, and healthy group with Wilcoxon/Kruskal-Wallis one-way analysis of variance and Dunn-Bonferroni test.

Dimethyl sulfide, toluene, and dodecane obtained of newly-diagnosed APL patients were significantly higher, while ethanol, n-hexanal, and benzaldehyde were significantly lower than those of healthy people (P<0.05). Compared with the newly-diagnosed group, dimethylsulfide, toluene, and dodecane of the remission group significantly decreased, while ethanol, n-hexanal, and benzaldehyde significantly increased (P<0.05), which was just opposite from the relapse group.

Dimethyl sulfide, toluene, dodecane, ethanol, n-hexanal, and benzaldehyde can be used as biomarkers for the diagnosis and prognosis assessment of APL patients.

To investigate the effect of GÖ6976 on the proliferation of chronic myeloid leukemia cells and its toxic effect on normal cells and mice, so as to provide experimental basis for the effectiveness and safety of its clinical application.

Different concentrations of GÖ6976 were applied to the K562 cells, human peripheral blood mononuclear cells (PBMNC) and normal BaF3 cells, MTT assay was used to detect the effect on cell proliferation. BALB/C mice were used to investigate the toxicity in vivo. The general situation, body weight and the number of white blood cells in peripheral blood were monitored during administration, the blood collected from eyeballs before and after administration was used for biochemical examination, at the same time, the liver, kidney and femurs were examined pathologically.

GÖ6976 could significantly inhibit the proliferation of K562 cells, inhibition effect increased with increasing dose (r=0.9623). However, there was no significant change in the inhibitory effect on PBMNC and BaFproliferation of K562 cells, and the inhibitory effect increases with increasing dose. Long-term application of 5.0 μmol/L and below concentrations of GÖ6976 shows no obvious inhibitory effect on PBMNC, BaF3 cells. Long-term application of 10 mg/kg and below concentrations of GÖ6976 shows no obvious toxic effect on BALB/c mice.
To explore the possible risk factors of death in children with acute lymphoblastic leukemia (ALL) after treatment.

The clinical data of 31 children with newly diagnosed acute lymphoblastic leukemia and dead after treatment in the Hematology Oncology Department of Wuhan children's Hospital from January 1, 2016 to December 31, 2019 were retrospectively analyzed. Univariate factor analysis and multivariate Cox regression analysis were used to analyze the each indexes of ALL children, and the possible risk factors causes of death in ALL children after treatment were analyzed.

Among 230 newly diagnosed ALL children, 31 (13.4%) cases were dead. Among them, there were 12 male and 19 female. The mortality rates were 9%(12/133) for male and 19.5%(19/97) for female, which showed a significantly difference（P=0.02）； among the dead ALL children, 6 were less than 1 year old, 23 were 1-10 years old, and 2 was more than 10 years old. The mortality rates in different age groups were 46.1 % (6/13), 11.7%(23/195) and 9%(2/22), respectively, which showed a significantly difference（P=0.
